Radeon HD 7990

2013

Why buy it

✅23.4% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 5.6 vs 0 G3D/$ ($999 MSRP vs Unknown MSRP).

Trade-offs

❌Less VRAM, with 3 GB vs 4 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2013-era hardware with 3 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌341.2% higher power demand at 375W vs 85W.

Radeon Pro 5300M

2019

Why buy it

✅33.3% more VRAM for high-resolution textures and newer games (4 GB vs 3 GB).
✅Less risky long-term buy than Radeon HD 7990: it remains the more sensible modern option while Radeon HD 7990 is already obsolete for modern gaming.
✅Draws 85W instead of 375W, a 290W reduction.

Trade-offs

❌Lower average FPS than Radeon HD 7990 across 50 tracked games in our benchmark data.
❌Limited future-proofing: older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.
❌Lower G3D Mark per dollar, at 0 vs 5.6 G3D/$ (Unknown MSRP vs $999 MSRP).

Quick Answers

So, is Radeon Pro 5300M better than Radeon HD 7990?

Yes. Radeon Pro 5300M is clearly the better overall GPU here. Radeon HD 7990 averages 23.4% more FPS across 50 tracked games in our benchmark data. You are also looking at 5,853 vs 5,566 in G3D Mark. On top of that, Radeon Pro 5300M is a 2019 card with FSR upscaling, while Radeon HD 7990 is a 2013 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

Which one is more future-proof for 2026 and beyond?

Radeon Pro 5300M is the more future-proof choice for 2026 and beyond. You are getting a newer 2019 generation instead of 2013, more VRAM at 4 GB instead of 3 GB, and a 7nm process instead of 28nm. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

Which one is the smarter buy today, not just the cheaper card?

Radeon Pro 5300M is the smarter buy by a wide margin. Radeon Pro 5300M is priced in an unclear MSRP range at an unclear MSRP versus $999 MSRP, and you are getting lower estimated average FPS across 50 tracked games in our benchmark data and 5.2% higher G3D Mark. Radeon HD 7990 really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is Radeon HD 7990 still worth buying for gaming in 2026?

No, not for a fresh gaming build. Radeon HD 7990 is 2013 hardware with 3 GB of VRAM, 5,566 in G3D Mark, and FSR upscaling. That is simply too far behind to be an easy modern recommendation.
